Description
The Copeland 060934 Oil Separator (Model A-W55855) is a precision-engineered refrigeration component designed to remove entrained oil from the refrigerant discharge stream before it circulates through the system. By returning oil efficiently to the compressor crankcase, this separator helps maintain proper lubrication, protects compressor longevity, and maximizes heat transfer efficiency throughout the refrigeration circuit.
Key Features
- 5/8″ welded connections for secure, leak-free installation
- 450 PSI maximum working pressure rating for reliable performance in demanding applications
- Welded construction provides superior durability and pressure integrity
- Designed to efficiently separate and return compressor oil, reducing oil carryover into the refrigerant circuit
- Compatible with Copeland compressor systems and a wide range of refrigeration applications
- Compact design for straightforward field installation

Why Use an Oil Separator?
Oil separators are a critical component in commercial and industrial refrigeration systems. Without effective oil separation, compressor oil can coat heat exchanger surfaces, reducing thermal efficiency and increasing energy consumption. The Copeland A-W55855 helps ensure that oil is continuously returned to the compressor, maintaining optimal lubrication and extending equipment service life.
Applications
- Commercial refrigeration systems
- Air conditioning and heat pump systems
- Industrial refrigeration circuits
- Systems utilizing Copeland compressors requiring reliable oil management
